So the rules for using a staff state:
"You can Cast a Spell from a staff only if you have that spell on your spell list, are able to cast spells of the appropriate level, and expend a number of charges from the staff equal to the spell’s level." (page 592)
My question lies with this particular scenario:
I am a level 10 Sorcerer with the Elemental Bloodline, I have just picked up the feat Bard Dedication http://2e.aonprd.com/Feats.aspx?ID=677.
As a sorcerer with the Primal Tradition I am able to cast spells from this list up to level 5 spells.
With bard dedication, I am able to cast Occult cantrips and gain access to the Occult spell list.
If I equip a Staff of Divination http://2e.aonprd.com/Equipment.aspx?ID=353, am I allowed to cast "True Stike", a level 1 spell from the Occult spell list?
Breaking down the staff rules:
1. You can Cast a Spell from a staff only if you have that spell on your spell list.
-Yes I have access to the Occult spell list.
2. are able to cast spells of the appropriate level
-Yes, but they are Primal spells up to level 5.
3. and expend a number of charges from the staff equal to the spell’s level.
-I would be able to add 5 charges to the staff being a level 10 Sorcerer.
So with these points being satisfied, am I able to cast True Strike from the staff? Or must my "are able to cast spells of the appropriate level" come from a spell's particular tradition?
